Keyboard
Operations
All keyboard operations take place on the display page at the current
cursor position. As a character is entered, the cursor moves one position
to the right. In block mode, the Esc key is disabled.
The Ctrl key does not generate ASCII control codes as in conversational
mode (except for 50 and 51).
Only the function keys transmit codes to the host. The remaining keys
typically perform a local action within the display page, as described in
Table 3-12. As noted in the table, the keyboard operations function
somewhat differently in protect submode.
When the 6530 is in insert mode (entered by pressing the Alt-Ins keys),
all characters entered from the keyboard are inserted by moving existing
characters to the right to make room for the new characters. Characters
pushed off the end of the line (nonprotect submode) or the end of the field
(protect submode) are lost. The 6530 cannot be placed in insert mode
from the host. Insert mode has no effect on data written to the 6530 by
your application.

column of the next line. If the cursor is initially in the last line
of the page and the last column of the line contains a
character, the cursor moves to this column.
In protect submode, moves the cursor to the column
following the last nonblank character in the current field. If
the last position of the field contains a nonblank character,
